ACR Poker OSS XL: $50M+ GTD, 336 Events & Leaderboards

ACR Poker has been part of the online poker landscape since 2001 and remains a major destination for players in the U.S., Latin America and other international markets.

The room has built its reputation around large tournament guarantees, high-profile series and creative formats. A broad rewards offering also includes rakeback, reload bonuses and leaderboard promotions.

Right now, the focus is firmly on the Dual Mystery Bounty Venoms, with ACR Poker’s flagship events entering their most exciting stage. The $2,650 buy-in will be out of reach for many players, but PokerStrategists do not have to sit on the sidelines.

ACR Poker is preparing another festival packed with lower buy-ins and plenty of added value. Therefore, players who do not want to spend $2,650 on a Venom entry still have another way to stay involved in the action.

OSS XL Brings $50M+ in Guarantees

Americas Cardroom is turning up the volume in September with OSS XL, a supersized online tournament festival running from September 6 to 29.

The series comes with more than $50 million guaranteed across 336 tournaments. The schedule covers everything from affordable qualifiers to $25K High Rollers.

Three Main Events, four major multi-flight tournaments and a leaderboard race worth more than $60,000 add even more value to the festival.

OSS XL Quick Facts

• 📅 Dates: September 6–29
• 💰 Guarantees: More than $50 million
• 🏆 Tournaments: 336
• 🔥 Main Events: 3
• ✈️ Major Multi-Flights: 4
• 💎 Nosebleed Events: 10

• 🎟️ Satellites: Plenty of low-cost routes into bigger events

Three Main Events With $5 Million Guaranteed

The biggest targets on the OSS XL schedule are the three Main Events, which combine for $5 million in guarantees. They also cover three very different bankroll levels.

The two biggest versions begin on September 20, with another starting flight one week later. Day 2 follows on September 28, while the final table takes place on September 29.

• 🏆 $2.5M GTD Main Event: $2,650 buy-in
• 💰 $2M GTD Main Event: $1,050 buy-in
• 🎯 $500K GTD Main Event: $66 buy-in

Players looking for a much cheaper route can target the $500K GTD Main Event for just $66. Day 1 flights run on September 13 and 20, with Day 2 scheduled for September 27.

Even the $66 entry can be avoided through $6.60 satellites. As a result, one of the festival’s biggest tournaments becomes accessible to much smaller bankrolls.

$2.225M Across Four Multi-Flight Events

OSS XL also features four large multi-flight tournaments sharing $2.225 million in guarantees.

The headline event is a $1.5M GTD tournament with a $630 buy-in. Day 1 flights run throughout the series before Day 2 on September 28.

Three Mystery Bounty Events

Three Mystery Bounty tournaments complete the multi-flight lineup:

• 🎁 $500K GTD Mystery Bounty: $109 buy-in
• 💰 $150K GTD Mystery Bounty: $33 buy-in
• 🔥 $75K GTD Mystery Bounty: $5.50 buy-in

With buy-ins stretching all the way down to $5.50, the multi-flight schedule gives lower-stakes players a realistic shot at substantial prize pools.

$60K+ OSS XL Leaderboard

The OSS XL Leaderboard Competition gives players another reason to stay active throughout the series. More than $60,000 in cash and tournament tickets will be available from September 6 to 29.

Instead of putting every player into one race, ACR Poker splits the competition across three separate leaderboards for High, Medium and Low buy-ins. Therefore, players at different stakes have a realistic chance to climb the rankings and earn additional rewards.

Better still, the entire leaderboard prize pool is funded by ACR Poker. That means the promotion adds extra value on top of the regular OSS XL tournament payouts.

How the OSS XL Leaderboard Works

• 🏆 Play eligible OSS XL tournaments from September 6–29
• 📈 Collect points based on finishing position
• 🔥 High Leaderboard: Buy-ins of $104.50 and above
• ⚡ Medium Leaderboard: Buy-ins from $16.50 to $88
• 🎯 Low Leaderboard: Buy-ins under $15
• 💰 Chase a share of $60,000+ in cash and tournament tickets
• 🎁 The leaderboard prize pool is fully funded by ACR Poker

By separating the competition into three buy-in levels, OSS XL gives players across a much wider range of bankrolls a genuine chance to compete for extra rewards.

For regular OSS XL grinders, this makes volume even more valuable. Strong results can pay twice: once through the tournament prize pool and again through the leaderboard standings.

Nosebleed Week Takes Over

At the opposite end of the spectrum, ACR Poker is dedicating part of the festival to serious high-stakes action.

From September 21 to 28, OSS XL will host 10 Nosebleed Stakes tournaments, with buy-ins ranging from $5,000 to $25,000.

That creates a strong contrast across the series. Recreational players can start for only a few dollars, while established High Rollers get a full week of five-figure buy-ins.

More OSS XL Tickets Through The Beast

ACR Poker’s long-running The Beast promotion will also connect directly with OSS XL throughout September.

Players can compete for $1,050 and $2,650 tournament tickets, providing another route into the festival’s biggest events without paying the full buy-in directly.

More US-Friendly Start Times

ACR Poker is also adjusting parts of the OSS XL schedule to better suit its core U.S. audience.

More tournaments will start at US-friendly times. As a result, American players should have more opportunities to take part without having to play deep into the night or early morning.

With $50M+ guaranteed, 336 tournaments, three Main Events and buy-ins ranging from $5.50 to $25,000, OSS XL is shaping up as one of ACR Poker’s biggest online festivals of the year.

Why OSS XL Is a Must-Play Series

OSS XL stands out because it combines serious prize pools with buy-ins for almost every bankroll. Players can start with low-cost satellites and $5.50 Mystery Bounties. Meanwhile, the schedule still offers million-dollar guarantees and high-stakes events for experienced grinders.

The sheer variety also creates value. 336 tournaments, $50M+ guaranteed, three Main Events, major multi-flights and extra ticket opportunities through The Beast mean there are plenty of ways to find a suitable spot without relying on one marquee event.

For tournament players looking for big guarantees, accessible entry points and a deep September schedule, OSS XL ticks almost every box. Both casual players and regular grinders can find significant value throughout the series.
